`In this study, Thalassiosira weissflogii was transformed into biohybrid microrobots (Mag-Diatoms) while retaining its natural chlorophyll, thereby enabling Mag-Diatom-mediated photodynamic therapy (PDT) without additional drug modification.`

#DidYouKnow:A #Diatom is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world.

Living diatoms generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion tonnes of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans.

We interrupt the planned programming to let everyone know we have a new paper out! 🚨
Led by Cécile Figus, this work explores what governs the distribution of deep #sea sediment rich in #diatom across the #Paleogene.

After 7,000 years without light and oxygen in #BalticSea mud, researchers bring prehistoric #algae back to life https://phys.org/news/2025-03-years-oxygen-baltic-sea-mud.html

Resurrection of a #diatom after 7000 years from anoxic Baltic Sea sediment: Sarah Bolius et al. https://academic.oup.com/ismej/article/19/1/wrae252/7942337

"Such deposits are like a time capsule containing valuable information about past ecosystems and the inhabiting biological communities, their population development and genetic changes"

The #diatom genus Nitzschia lost photosynthesis to become free-living heterotrophs. This study shows how #HGT from marine bacteria, followed by #GeneDuplication & #neofunctionalization, allowed them to catabolize #alginate & live off brown algal polysaccharides @PLOSBiology https://plos.io/41WaW8e

Delighted to see our work on #diatom motility published in @pnas.org !🎉 doi.org/10.1073/pnas... These abundant single-celled algae are responsible for a significant portion of the air we breathe yet often overlooked. Here we show how how diatom (raphe) shape impacts their gliding function... 1/3

#Phytochromes: The 'eyes' that enable #microalgae to find their way in aquatic depths https://phys.org/news/2024-12-phytochromes-eyes-enable-microalgae-aquatic.html

#Diatom phytochromes integrate the underwater light spectrum to sense depth: Carole Duchêne et al. https://www.nature.com/articles/s41586-024-08301-3

"These photoreceptors enable them to detect changes in the light spectrum in the water column, thereby providing information regarding their vertical position within it."

I am very happy to share this new paper led by Cécile Figus, which shows the very complex relationship between #diatom prevalence in #Paleogene epicontinental seas, #tectonics, and global #climate.

So proud of #USFCMS graduate student Christina Chadwick, who did her Master’s degree with me and Katherine Hubbard looking at Pseudonitzchia (#phytoplankton #diatom) diversity, toxin levels, and environmental parameters in the Gulf of Maine - her research will help in understanding the drivers of these harmful algae blooms. Christina is highlighted among this weekend’s #USF graduates - https://www.usf.edu/news/boundless-bulls/students/grad-series-spring-2023.aspx #graduation #science #ocean
